Sweet birch, a tree of the forests of eastern North America, was well known to Indigenous peoples and early settlers for its aromatic bark with a wintergreen scent. It once yielded a sweet sap and a bark used in rubs and teas, a heritage passed down in folk herbalist notebooks.

Precautions

Before you use it

Contains natural salicylates: to be avoided in cases of aspirin allergy, clotting disorders, before surgery, or during pregnancy and breastfeeding. Never give to children, because of the risk of Reye's syndrome associated with salicylates. The essential oil extracted from the bark is highly concentrated in methyl salicylate and can be toxic even in small amounts internally or as undiluted skin contact; its use is discouraged without supervision by a qualified professional. Seek the advice of a health professional before any internal use, particularly if undergoing anticoagulant or anti-inflammatory treatment.
